5 arrested for plotting attacks in Moscow, Russia's Caucasus

MOSCOW – The Russian intelligence agency FSB says it has arrested five people allegedly linked to the Islamic State group who were suspected of plotting terrorist attacks in Moscow and Russia's Caucasus.

The FSB said in a statement on Tuesday that its officers found five firearms, two improvised explosive devices, each with the equivalent of 10 kilograms of TNT, and various types of ammunition at the suspects' homes. The FSB did not say if the arrests were made in Moscow or the region of Ingushetia in the North Caucasus where the men were believed to be planning attacks.

Islamist insurgency spread to Russia's Dagestan and Ingushetia in the early 2000s after the end of the war in Chechnya.
